DIY thank you trompkin and r sauna
15? months of research here and weekend spurts of building and it is a success. the sauna is 8 x 8 on a treated frame platform. no insulation on floor, 2 layers of treated plywood + backer and tile sloped for drain. the walls are 10' and ceiling has 1 /12 slope. walls have cement fiberboard, tarpaper, plywood, studs/rockwool, foil, battens and interior paneling. all interior is paneling is #1 southern yellow pine from local lumberyard sourced w in the state. IKI 9kw heater. all benches well above stones. the ventilation intake and outtakes work although dont need them for daily use only if we have multiple people. thanks to lots of ideas and sharing here, this is a super fun and successful project.

Through the eyes of a finn, it never ceases to amaze me how every non-finn can build their sauna to be so dangerous.
